In the low-low satellite to satellite gravity mission, the intersatellite range and range-rate data are the observable values, while the intersatellite acceleration can be derived from the range-rate through digital differential. Using acceleration data, people can avoid solving the variation equations of the satellite motion and simplify the observation equations. But on the other side, the digital differential will amplify the observation noises and finally affect the solved geopotential accuracy.

低低卫星跟踪卫星的观测量是两低轨卫星的星间距离或星间速度，星间加速度由星间速度通过数值微分导出，用星间加速度作为观测量可以避免解算卫星运动的变分方程，简化观测方程的建立，但数值微分会使观测噪声放大，从而影响重力位的解算精度。

In order to understand the adaptation of the microorganisms under the extreme cold environment conditions, the physiological characteristics of the 5 bacterial isolates from the Muztag Am ice core under the different temperatures were investigated. The csp gene was also amplified by PCR technique and the specific primer targeted for the cold shock protein. The observation results showed that there were three phenotypes of microorganisms: psychrophiles growing from 0~23°С(the optimum temperature at 15°C), psychrotolerant with growth range at 0~40°C (the optimum temperature at 23°С), and the thermophile with growth range at 0~45°C(the optimum temperature at 30°C).

为了解冰川微生物的生理生长特征及其在极端寒冷环境条件下的冷适应特性，从慕士塔格冰芯分离菌株中选取了5个代表菌株，分别对这些菌株的生长温度和酸度范围进行了观测，并利用微生物冷诱导蛋白的保守氨基酸序列，设计了1对冷诱导基因csp的特异引物，并对其进行了PCR扩增。

Requires extraordinary technical proficiency of the ball, running fast, skilled with the ability to have long-range, and shot a breakthrough technology Qiangdian outflanking shot. In the 1970s, the scope of their duties and activities of a more expanded offensive will no longer be limited to activities within the scope of this position, but often in the middle of the cut, play the role of the center, or with different side of the wing for a wide range of The cross, or retracement from midfield to the role of the avant-garde in order to achieve a variety of effective tactics to attack with.

要求具备熟练的带球过人技术，有快速奔跑、熟练配合的能力，并具备远射、突破射门及抢点包抄射门的技术。20世纪70年代以后，其职责和活动范围更为扩展，进攻时不再仅限于本位置范围内活动，而是经常向中间内切，起到中锋的作用，或与异侧的边锋作大范围的交叉，或回撤至中场起前卫的作用，以实现各种有效的进攻战术配合。
